I installed VS2005 last November and at around that time a program in VS2003
stopped behaving. I've recently found the time to dig into this, and one of
the things I've just noticed is that the DLLs that the program loads (which
are managed C++, written in VS2003) in turn load 2.0.50727 runtimes (such as
mscorlib and msvcr80).
Could this be the reason for problems or is it expected behaviour that a DLL
built in VS2003 uses the .net 2 and VC80 DLLs if available?

On an aside, how can I find out what the value of $(FrameworkVersion) is,
and is it possible to change it?

Thanks, all
Eric T.

Hi Eric,

Do you have .NET framework 2.0 and 1.1 installed on the same machine? Or
you have only installed .NET framework 2.0 on that machine?

If only .NET framework 2.0 is installed, the app will automatically use the
.NET 2.0 CLR to load it.

I have both installed. VS2003 with .net 1.1 and VS2005 with .net 2.0. The
DLL that causes the loading of the 2.0 runtimes was compiled with VS2003 and
meant to go with 1.1.

Hi Eric,

Would you try to add a line of code in your app to print out what version
of runtime the app is using? You can use System.Environment.Version to
display it. HTH.

Pardon for butting in. Is there a directive you can place on the app so that
it uses one or the other framework versions?
